PERFORATING DEVICE.

Specification of Letters Patent.

Patented Apr. 27, 1920.

Application filed December 00, 1918. Serial No. 269,012.

To all whom it may concern:

Be it known that I, CHARLES F. l\[oBEn, a citizen of the United States,residing at Athens, in the county of Athens, State of Ohio, haveinvented a certain new and useful Improvement in Perforating Devices, ofwhich the following is a specification.

The object of my invention is to provide a punch or perforating device,adapted to insure registration of the punch shaftsswith the receivingorifices when the said shafts become slightly displaced and out of line.My device is designed particularly for that class of punches wherein thepunch post, or shaft, is of some considerable length, for it is in suchconstructions that slight displacements are frequent, and result inimperfect and improper operation of the punch or render it completelyinoperative.

My invention consists of certain details of construction hereinafter setforth, pointed out in my claims and illustrated in the accompanyingdrawings, in which Figure 1 shows a front elevation of my device,partially in section, and

Fig. 2 shows a side elevation of the same.

Referring to the accompanying drawings the reference numeral 10 is usedto indicate the base of the punch, with vertical tubular posts, 11 and12, mounted thereon to receive guide shafts, 13 and 14: respectively,designed to be actuated by springs 15 and 16 mounted in the orificesbelow the said shafts, as shown. The numerals l7 and 18 indicate slotsin the said posts to receive lugs 19 and 20 respectively, secured to theuide shafts, thus providing means to limit 0th the upward and downwardmovement of the guide shafts in their mountings. The said guide shaftsextend downwardly from a plate 21 which is provided with orifices 22 toreceive punch shafts 23 extending upwardly from, and secured to, thebase 10. These said orifices are beveled at their lower ends, at 24:, asclearly shown. The numeral 25 indicates a handle on the plate 21.

In a punch requiring long punch shafts it frequently occurs that theshafts, by reason of their length, get slightly out of register withtheir receiving orifices, and it is practically impossible to repairsame. By reason of slightly beveling, outwardly, the receiving orifices22 if the punch shaft 23 should be slightly out of true it will still bereceived by the beveled surface and directed through the orifice and thepapers be perforated. By practical usage it has been demonstrated thatthis construction is very satisfactory and positively accomplishes theobjects sought.

Having thus described my invention what I claim and desire to secure byLetters Patent of the United States, is:

1. A punch comprising a base provided with perforating shafts near itsouter end, a plate provided with perforating shafts, beveled orificesnear its outer end adapted to receive said perforating shafts, saidplate having guide shafts adjacent the inner side of the punch shafts,there being orifices in the base provided with springs adapted toactuate the said guide shafts, said base being provided with posts toreceive said guide shafts.

2. A punch comprising a base having elongated perforating shafts; areceiving member for said shafts, provided with receiving orifices thelonger portion of their inner surfaces being in a vertical line thelower portions thereof being beveled outwardly, guide posts located onthe inner side of the perforating shafts, there bein orifices withinsaid base and means in sai base adapted to actuate said guide shafts,substantially as shown and described.

3. A punch comprising a base, provided with punch shafts near its outerend, a plate provided with orifices near its outer end adapted toreceive said punch shafts, said plate having guide shafts adjacent theinner side of the punch shafts, there being orifices in the baseprovided with springs adapted-to actuate the said guide shafts, saidbase being provided with tubular posts to receive said guide shafts.

1. A punch comprising a base, provided with punch shafts near its outerend, a plate provided with orifices beveled outwardly at their lowerends, adapted to receive said means to limit both the upward anddownpunch shafts, said plate having guide shafts Ward movement of theguide shafts. adjacent the inner side of the punch shafts, In testimonywhereof I have signed the there being orifices in the base providedforegoing specification.

With springs adapted to actuate the said CHARLES F. MOBEE.

guide shafts, said base being provided With W'itnesses: tubular posts toreceive said guide shafts, L. D. VoRE, and a handle attached to saidplate, and H. R. RAMSEY.
